Description Frank Osterfeld 2004-11-19 11:51:52 UTC

Qt 3.3.3 
KDE CVS, 3.3 branch 
Gwenview: current CVS (2004/11/19) 
 
When I view a large file like (2MB compressed, approx. 8000x8000 pixels) 
 
http://static.capsi.com/blog/kde.dot.ps.jpg 
 
gwenview eats a huge amount of RAM: 
 
... 519396 390796 ... gwenview 
 
where GIMP needs much less:  
 
... 91160 86680 ... gimp-2.0 kde.dot.ps.jpg 
 
In version 1.0.1 it seemed even worse - loading the file froze my system (512 
MB RAM) nearly completely until I was able to killall gwenview.

The picture is no longer available. When testing here with another 8000x8000, Gwenview needs about 256M memory, which is normal (8000x8000x32bpp is 256M). It seems comparable to what GIMP needs. Computer thrashed to death due to swapping is indeed not nice, but that's a kernel problem.
Reclassified as a wish.

Closing, because it's old and very likely fixed.
